Video data transmission code rate adaptive method, system, device and storage medium

Abstract

The invention discloses a video data transmission code rate adaptive method, system, device and storage medium. The method includes obtaining each actual return value and each actual network state value fed back by each terminal, and converting each actual return value and each The actual network state value is stored as historical experience, historical experience is randomly extracted to perform temporal difference training on the predictive neural network, the network observation state value of the first time window is obtained to input to the predictive neural network, and the output of the predictive neural network is received Each predicted return value, and the steps of determining the code rate level corresponding to the optimal value among each said predicted return value. By using the predictive neural network to classify the network observation state values ​​collected in real time, the optimal bit rate level is selected for communication. The bit rate level output each time is the optimal decision at that time, which can overcome the difficulties of existing technologies. Adapt to the shortcomings of different network environments. The invention is widely used in the technical field of Internet.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a video data transmission code rate adaptive method, system, device and storage medium. Background technique [0002] The video playback services provided through the Internet are becoming more and more abundant, and the requirements for Internet hardware devices are also getting higher and higher. The basic process of providing video playback services on the Internet is: the video communication server sends video data to the terminal through the Internet, and the terminal plays the video data. Therefore, the quality of video playback is closely related to the quality of video data transmission. The bit rate is an important index to measure the video data transmission process. Too low bit rate will seriously reduce the quality of video playback, and too high bit rate will increase the load on Internet hardware devices, and even fail due to poor network environment. achieve....

Problems solved by technology

However, the limitation of this technical solution is that it is only suitable for one-to-one streaming media applications, that is, the scene where the video communication server only transmits video data with one terminal, but in practical applications, the video communication server will face the concurrent communication, which is beyond the scope of this technical program
